I felt playing another terry wad, but worse.
You should work with textures and the idea of it, not just placing spectres everywhere with a trigger action to spawn a cyberdemon.
EDIT: Why you been working on this map for 10 Hours?
That's actual looks like a 15 minute made map.

Too much enemies on start which makes normal difficulty to harder than MAP12.
Here's low medical and weaponary supplies which makes a bit harder but, I loved how map was designed!I hate heres a lot of traps around this map because I needed to be careful as heck!
Anyways!
Its good map! Just don't add more traps.
